6 sources for · 0 against

Flight times differ noticeably between eastbound and westbound journeys because aircraft operate within atmospheric wind patterns like the jet stream, which provide tailwinds or headwinds depending on the direction of travel.

Evidence for · 6
Transatlantic flight times and climate change
2016 · cited by 84
The study investigates transatlantic flight routes and confirms that prevailing jet-stream winds cause eastbound flights to significantly shorten and westbound flights to significantly lengthen.

The analysis

The retrieved papers consistently demonstrate that upper-level winds, specifically the jet stream, create significant differences in flight duration between eastbound and westbound routes due to tailwinds and headwinds. There are no papers contradicting this well-established meteorological and aviation principle.

The paper notes that minimum-time routes exploit wind fields, showing substantial differences in air distances and journey times between east and west directions.
What are the implications of climate change for trans-Atlantic aircraft routing and flight time?
2016 · cited by 28
Research highlights that upper-level winds over the north Atlantic, specifically the jet stream, strongly influence optimal flight routes and result in different flight times for eastbound and westbound journeys.
Impact of climate variabilities on trans-oceanic flight times and emissions during strong NAO and ENSO phases
2020 · cited by 15
The study demonstrates that intensified jet streams provide stronger headwinds for westbound flights and alter trans-oceanic round-trip flight times.
